A TTORIVE V CHARLES H. NIXON, OF DETROIT, MICHIGAN.

ADJUSTABLE HINGE.

To all whom it may concern:

Be it known that I, CHARLEs H. 'NIXON, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented a new and useful Adjustable Hinge, of which the following isaspecification.

This invention relates to hingesespecially adapted for use in mountingswinging doors of buildings. 7

The invention has for its object the provision of a hinge of simple andcomparatively inexpensive construction which may be readily applied inthe usual way, but with greater facility in effecting the proper hangingof doors, in which provision is made for pivotally connecting the leavesof the hinge in a manner to render them bodily removable relativelyso asto enable adjustments to be made to compensate for variations in thedoor or casing and insure an even fitting and free swinging of the door.

In attaining the above object the invention contemplates, brieflydescribed, the employment of a pair of hingeleaves each having pintleknuckles and which are joined in adjacent parallel relation byintercon-v necting links interposed between the pintle knuckles. -Theends of the links engaged with the stationary leaf ofthe hinge freelyembrace the pintle thereof and form the pivotal bearings upon which thecompanion leaf of the hinge swings, while the ends of the links engagedwith the swinging leaf tightly embrace the pintle thereof undersufficient frictional stress to normally prevent pivotal movement of theengaged parts, yetyielding under the application of undue stress topermit of the shifting ofthe pintle about the pivotal axis of thestationary hinge to varythe distance between the leavesv withoutaltering their parallel relation or disturbingtheir fixed positions uponthe stationary and swinging members.

A preferred structural embodiment of the essential features of thepresent invention is illustrated in the accompanying drawings,

in which,

tive of portions of the hinge members disengaged.

Fig. 4c is a vertical sectional view through the hinge knuckles andconnecting links on dotted line fl 4: of Fig. 2.

Referring to the parts by the characters of reference marked on thedrawings, 1 represents the frame or jamb of a doorway within which thedoor 2 is hinged to swing, 3 indicates a stop for the door and 4 thecasing for the door frame, all of which is common.

The body of the hinge consists of two plates or leaves 5 and 6preferably stamped to form of sheet metal and provided with holes 7 forthe reception of screws 8 by which said leaves are attached respectivelyto the jamb and door being seated in mortices formed therein in theusual way. See Fig. 2. The stationary or jamb leaf 5 is provided at itsouter edge with a series of spaced axially alined pintle knuckles 9which are offset to overlie the plane of the inner face of the leaf byan arcuate extension 10, and the outer edge of the swinging or door leaf6 is provided with a series of correspondingly spaced pintle knuckles 11which normally nest within the arcuate extension of the leaf 5 and liein adjacent transverse alinement parallel with the knuckles 9 thereof.

Inserted in the registering spaces between the knuckles of the hingeleaves to extend transversely thereof is a connecting link or links 12,each comprising two parallelly connected knuckles which lie in axialalinement with corresponding barrels of the leaves and receive therespective hinge pintles 13 and 14 which are extended through saidknuckles, as shown in Figs. 1 and 4c. The pintle 18, which extendsfreely through the knuckles of the stationary leaf and the connectinglinks, forms the pivotal axis on which the links turn together with theswinging leaf and door carried thereby, and the body of this pintle,which is preferably removable, is divided near one end and provided witha cap or plug 15 fixed in a knuckle of the hinge in the usual way. Thepintle 1a connecting said'links with the door leaf is made.

ment of the members forming this joint when subjected to added stressunder the application of leverage force or impact -to break the jointand change the angular relation-of the. linksand door leaf so asto-effect an adjustment bodily of the leaves of the hinge.

Under ordinary conditions the frictional contact afforded .by a 'tightfit of the pintle 14 within the knuckles of the links andadoor leaf issufiicient to retain them in set relation against accidentaldisplacement, but ,in certain uses of the hinge,,as when carryingunusually heavy doors, it .may be desirable to fixedly secure one ormore of the links to the 'pintle '14 in order 'to more positively bringinto service the frictional surfacesof the knuckles of'the door lea-fwhich collectively embrace the p'intle over agreatenbearing surface thanthat afforded by the knuckles of the links, and thus resistance to theturning of the'connected members of the joint will be'increased. Thismay "be-effectively accomplished by inserting a I in transverselythrough the knuckle of the link and pintle as indicated at 16. "See Fig.4.

Where smaller hinges for lighter wor'k are required the hinge leaves maybe formed with a single pair of spaced knuckles "forthe reception of -asingle connecting link in which the p'in'tle of the swinging leaf may betightly fitted therein and in the knuckles o-f the leaf, or itmay be'fixedly secured in the link knuckle by means of a pin as may bedesirable to regulate the frictional re sistance of the joint.

From the foregoing description of the construction the operation of thehinge should now be understood as follows: It will be-noted that thedoor leaf and connecting link normally "swing together upon the pintleof the stationary leaf, and .as the angular position'of the connectinglink to the plane of'the door leaf determines the nested or spacedrelation of the two leaves-it will be appare-ntthat byexertingsufiicientforce upon-the link to turn it to the desired angleupon the pintle of the door leaf the space between the leaves may bevaried to shift the door transversely and effect an adjustment' thereofto secure the proper fitting or clearance with the jamb or leasing. Thismay be readily accomplished without'disengaging the hinge ornecessitating the disengagement or adjustment of any of the partsthereof further than to drive or force the knuckle of the link into orout of the arcuate extension of the jamb leaf to effect an adjustmentcorrespondingly of the door leaf and door.

I claim:

1. A hinge comprising two' leaves, and a to by link pivotally connectedto each of said leaves, said link "having fixed engagement with the,pivotal connection of one leaf and restrained against movement relativethere- .frictional engagement of .the pivotal connection with said leaf.

2. A h-inge having two leaves each provided with a pair of spaced pintleknuckles, a link interposed between the knuckles and connecting saidleaves, a pintle "forming a pivotal connection between said link and theknuckles of one leaf, and 'a pintle tightly embraced said link and theknuckles of theao'ther of said leaves and ;fr ictiona'-lly 11'6-straining said members against pivotal movement. e

'8. A hinge havingtwo leaves each pro vided with apa-ir ofcorrespondingly spaced pintle' *knuckles, the knuckles ofone leaf beingoifset to overlie the-plane-o'f the face of said leaf by an arcuateextension; embracing the knuckles of the companion lea'f, a connectinglin'k havin-g knuckles interposed -respectively between the knuckles of'said leaves, and pintles pivotally connecting the knuckles of said link with the respective knuckles of .Sitil leaves, one *of said pintlesbemg'restrame'd agamst pivotal movementby frictional engagement withthe-embracing knuckles. I
